| 摘 要： | 某框架剪力墙结构工程初期施工中,出现了楼板对角裂缝和跨中裂缝.经从结构、构造和施工多方面分析,主要是因板的抗裂能力不足引起的.后续施工中,采取在楼板上部加配双向抗裂构造钢筋网片、调整混凝土组分材料和配合比、改善混凝土性能的综合措施,成功解决了问题.

| Abstract: | Some floor diagonal cracks and mid-span cracks appeared in initial construction period of a frame-shear wall structure.By comprehensively analyzing from structure to construction,the crack is caused by the deficiency of crack resistance capacity of the floor.Then,the following measures are taken: such as configuration of bidirectional crack resistance reinforced,adjustment of components materials and mix proportion of the concrete,improvement of the concrete characteristics.The crack problem is resolved successfully. |
